Patented July 2, 1935 v UNITED STATES COMMODITY WRAPPER Shy Rosen, Flushing, N. Y., assignor to Milprint Products Corporation, Milwaukee, Wis., a corporation of Delaware Application May 24, 1934, Serial No. 727,287

8 Claims.

The present invention relates in general to improvements in the art of producing wrappers for diverse commodities, and relates more specifically to improvements in the construction of moisture-proof and otherwise protective flexible wrappings formed of sheet material.

Generally defined, an object of the invention is to provide a simple yet durable wrapper for various commodities, which is highly protective and which can be readily manufactured and applied to successive objects.

It has heretofore been common practice to wrap certain commodities such as chocolate bars in double or compound wrappers, the inner wrapping being formed of a single translucent sheet uniformly colored to simulate the external appearance of the commodity, and the outer or covering wrapping comprising a composite sheet formed of parallel strips of relatively opaque sheet material separated by an intervening transparent strip of sheet material through which the adjacent portion of the inner wrapping is visible, thus giving the general impression that the wrapped article is directly viewable through the window formed by the transparent strip. The opaque strips of the outer wrapping may also be formed of translucent stock of any desired color, and these strips as well as portions of the transparent strip, are ordinarily provided with identifying printing and decorative borders for the window formed by the transparent strip. In fabricating the outer composite wrappings, the opposite edges of the medial transparent strip are adhesively attached to the adjacent edges of the opaque strips, and the successive wrappers are usually formed by severing sections from a continuous band or compound ribbon produced by adhesively connecting one longitudinal edge of the inner wrapper forming strip and a corresponding edge of one of the opaque outer wrapper forming strips. This interconnection between the inner and outer wrappers permits convenient handling of the compound wrapper during application thereof to the goods. Because of the difliculties in applying the windows to the outer wrappers of these prior structures, there is considerable waste of material, and the use of the double thickness of material throughout the entire areas of these prior wrappers furthermore enhances the cost of production thereof.

It istherefore a more specific object of the present invention to provide a new type of wrapper' which possesses all of the important advantages of these prior co'mpound wrappings,

but which can be produced at minimum cost and without excessive waste of material.

Another specific object of the present invention is to provide an improved single wrapper which embodies all of the advantageous features of an ordinary window wrapping, without necessitating perforation of the main wrapper at the window.

A further specific object of the invention is to provide a durable substantially single-ply wrapper especially adapted for the concealment of chocolate bars or the like, and means associated with the exterior of the wrapper for creating a local window effect and for simultaneously reinforcing the wrapper structure.

Still another specific object of the invention is to provide an attractive commodity wrapper which can be conveniently fabricated with minimum efiort and waste of stock.

An additional specific object of the invention is to provide an improved wrapper of the window type, wherein the difliculties encountered in the fabrication of ordinary continuous window wrappings, are entirely eliminated, and whereby a strong'final wrapping material results.

These and other objects and advantages of the invention will be apparent from the following detailed description. I

A clear conception of several embodiments of the invention, and of the mode of producing and of utilizing the improved single-ply window wrappers manufactured in accordance therewith, may be had by referring to the drawing accompanying and forming a part of this specification in which like reference characters designate the same or similar parts in the various views:

Fig. 1 is a plan view of a section of wrapper forming ribbon showing several successive wrapper areas, and comprising a main wrapper forming strip having a medial chocolate covered stripe covered by a strip of normally transparent material portions of which have been coated so as to provide a window on each wrapper section through which the chocolate color is visible;

Fig. 2 is a similar view of a section of a modifled form of wrapper forming ribbon, comprising a uniformly chocolatecolored main wrapper forming strip covered medially by a transparent strip having a coating thereon to provide a window on each individual wrapper through which the chocolate color of the main wrapper is visible;

v Fig. 3 is a similar plan view of a section of a further modified form of wrapper forming ribbon, comprising an uncolored main wrapper forming strip covered at its center by a transparent strip coated to provide a window on each of the successive wrappers, the window area. of the transparent strip being colored to simulate chocolate;

Fig. 4 is a similar plan view of a section of another modified form of wrapper forming ribbon, comprising a main wrapper forming strip having a medial chocolate colored stripe covered by a strip of opaque sheet material having local openings therein forming a window on each wrapper through which the colored stripe is visible; and

Fig. 5 is a side elevation of a chocolate bar packed n one of the improved wrappings.

While the invention has been shown and described herein as being applied to a wrapper for chocolate bars, it is not intended to restrict the scope by such specific embodiment, and some of the novel features may obviously be more generally applicable to the wrapping of other commodities.

Referring to Fig. l, the improved wrapper shown therein is formed of a ribbon 5 of normally uncolored translucent moisture-proof flexible sheet material such as glassine paper, having a chocolate colored stripe 6 extending along the center thereof; and a strip 1 of normally transparent moisture-proof flexible sheet material such as Cellophane, adhesively attached at the areas 8 to the exterior of the main ribbon 5 and disposed over the stripe 6. The major portion of the transparent strip 1 is covered by a blue coating 9 cooperating with gold borders H) which form local window areas through which the color of the stripe 6 is visible, thus giving an observer the impression that a chocolate bar is directly viewable through each of the areas The ribbon 5 and the strip 1 after being pasted or glued together, are cut into lengths as indicated by the dot-and-dash lines l2, to produce the individual successive wrappers, and the coating or printing may be applied to the outer surface of the wrapping material, either before or after the severing operation.

Referring to Fig. 2, the modified improved wrapper illustrated therein, is formed of aribbon l5 of uniformly chocolate colored translucent moisture-proof flexible sheet material such as glassine paper; and a strip ll ofnormally transparent moisture-proof flexible sheet material such as Cellophane, adhesively attached at the areas l8 directly to the exterior of the main ribbon I5 to cover the medial portion thereof. The major portion of the transparent strip I1 is covered by a blue coating l9 cooperating with gold borders 2!! which provide local window areas 2| through which the chocolate color of the ribbon I5 is visible, thus giving the desired impression that a chocolate bar is directly observable through each window area 2|. As in the case of Fig. 1, the ribbon l5 and the strip l1 after being fastened together, are severed into lengths as indlcated by the dot-and-dash lines 22, to produce the individual successive wrappers, and the desired coating or printing may be applied to the outer surface of this wrapping material, either before or after cutting.

Referring to Fig. 3, the further modified improved wrapper disclosed therein, is formed of a ribbon 25 of uncolored translucent moistureproof flexible sheet material such as glassine paper; and a strip 21 of normally transparent moisture-proof flexible sheet material such as Cellophane", adhesively attached at areas 28 directly to the exterior of the main ribbon 25 so as to cover the mid-portion of the latter. The major portion of the normally transparent strip 21 is made opaque by the application of a blue coating 29 and gold borders 3!], the latter providing window areas 3|. The inner surface of the strip 21 at the window areas 3|, is colored in any suitable manner to simulate chocolate, so that viewing these areas 3| from the exterior, will give the observer the impression that a chocolate bar is directly observable through each window. As previously described, the ribbon 25 and the strip 21 after being secured to each other, are severed into proper lengths as indicated by the dot-anddash lines 32 in order to produce the successive individual wrappers, and the external coating or printing may be applied to the outer wrapper surface, either before or after the severing operation.

Referring to Fig. 4, the modified improved wrapper disclosed therein, is formed of a ribbon 35 of normally uncolored translucent moisture-proof flexible sheet material such as glassine paper, having a central chocolate colored stripe 36 applied thereto; and a strip 31 of either transparent or opaque moisture-proof flexible sheet material such as either Cellophane or glassine paper, adhesively attached along areas 38 directly to the exterior of the main ribbon 35 to cover the colored stripe 36. If the strip 31 is formed of transparent material, the major portion thereof is preferably coated with a blue or otherwise colored coating 39 and gold or otherwise colored borders 40, the latter of which directly surround cut-out window openings 4| formed in the strip. With the strip 31 disposed over. the stripe 36, the window areas or openings ll make the chocolate coloring visible, thereby giving an observer the impression of a direct view of the concealed chocolate article. As heretofore indicated, the ribbon 35 and the strip 31 after being united, are severed into suitable wrapper lengths along the dot-and-dash lines 42 in order to produce the individual wrappers, and the coating 39, borders 40 and any other printed matter, may be applied to the external wrapper surfaces either before or after cutting.

Referring to Fig. 5, wherein is shown an object or article such as a chocolate bar,packed within a wrapper of the form shown in Fig. 1, it will be apparent that practically the same appearance will be produced by wrapping a similar article in wrappers of the form shown in Figs. 2, 3 and 4. When the article has been wrapped as indicated, the transparent strip 1 substantially covers the top and side portions of the article, but does not cover the back thereof which is in fact covered only by the main wrapper 5. The colored area 9 and the border ,lfl are visible from above, and the chocolate colored stripe 6 is visible through the window area I, as shown. The severed ends of the wrapper are folded beneath the article as indicated, and remain thus folded by virtue of the double thickness afforded at these ends by the superimposed wrapper 5 and strip 1.

In fabricating wrappers of the above described type, the main ribbon of material 5 is first properly prepared after which a continuous strip 1 of the desired material is glued to the main ribbon by applying glue to the edges of the strip 1 and placing the same in contact with the main ribbon along the areas 8. This glue may be applied in any suitable manner, and may be subsequently dried by heating or otherwise. The compound 'is visible to give the desired effect.

From the foregoing description it will be apparent that the present invention provides a simple wrapper having a window area therein through which a colored area simulating the external appearance of the object or'article, is visible. When the coloring at the window area is covered by the transparent sheet, the effect upon the observer is to produce a more natural appearance, than whenthe-window areas are exposed as in Fig. 4. Theme of an imperforate strip, also prevents subsequent tearing of the wrapper during handling, and the double thickness provided by the window bearing strip in each case, reinforcesthe wrapper at the place where such reinforcement is most needed. Any of the improved wrappers can be produced at far lower cost than thedouble wrappers heretofore utilized for the same purpose, and waste of material such as is inevitable with the prior wrappers having composite external layers, is entirely eliminated with wrappers constructed in accordance with the present improvement. The improved wrappers, however, possess all of the advantages of the prior wrappers, and

v have been found to be highly successful in actual use.

It should be understood that it is not desired to limit the invention to the exact details of construction and to the precise mode of producing the wrappers herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
